**Math app level 19**:

**Answer**: 21

**Solution**: power 0= 1

If there is any Doubt/discrepancy then please let me know in comments or you are unable to understand solution then I will surely help you.

Guys, 21 is not supposed to be the answer. Following the order of “PEMDAS” the final result is equal to 6,5.

I kept getting -3

First you must remember that every number squared to 0 equals 1 It is a mathematical law!!!

Try to write down the equation like this:

(1^5) +[(5^2) / (25^0)] -(5^1) =

1+ (25/1) -5 =

1+25-5 = 26-5 = 21

or: 1 + 20 = 21

You mean if the exponent is 0 whatever the quantity is equal to 1

I bet you meant 25

Hello

1^5+5^2/25^0-5^1=

1+25/1-5

1+25-5

26-5=21

RESPUESTA: 21

Your math is wrong. I’m honestly not even sure how you got 21 as an answer to begin with.

For those reading this that don’t know, the “^” symbol means “to the power of” symbolizing an exponent ie: 1^5 means 1 to the power of 5 or 1x1x1x1x1. order of operations is as follows: parenthesis, exponents, multiply, divide, add, subtract and is always to be solved from left to right. a simple way to remember is Please Excuses My Dear Aunt Sally.

1^5+5^2/25^0-5^1=x

1+5^2/25^0-5^1=x

1+25/25^0-5^1=x

1+25/1-5=x

26/4+x

6.5=x

this is how the equation should have been solved. please fix this

No, perché prima di risolve la divisione, e poi l’addizione e la sottrazione!

This!!

Though, it should be – 6.5 as 1 – 5 = – 4

25^0 is not 1

it’s just 0

Division and Multiplication are always done first. 1+(25/1) -5 = 1 +25 -5 = 21

Sir I know what your thinj BUT this just only a riddle a lot of ideas to be consider thank you

Mohon penjelasannya.

x(y) mean x power y

1(5) + 5(2) / 25(0) – 5(1)

1 + 25 / 1 – 5

1 + 20

21
