Question

What is this I’m stuck

Answer 1

1/3

Explanation:

Three things to know to do this problem:

To multiply numbers with the same base, add the exponents. See image.

To add fractions with the same denominator (bottom number), keep the bottom number and add the top numbers.

See image.

To "fix" a negative exponent (make it a positive exponent), "push" the whole thing (base and exponent) across a fraction bar. See image.

Answer 2

Answer: A

Explanation:

Because the terms that are being multiplied have the same base (3) you would simply add the exponents and then make that the exponent of 3.

Add exponents 2/5+-7/5= -5/5 = -1

So that would be 3^-1

Whenever you have a negative exponent, you move it to the bottom to make it positive:

1/(3^1) which is just 1/3 or A
