Question

I need help! And I need a reasoning as well

Answer 1

A & D

Explanation:

3^5 = 243

The only other equations that also equal 243 are A & D.

You can also break the exponent up.

(Ex: The exponent is 5. You can split it by having 1 & 4 or 2 & 3)

(Ex continued: The number 3 must be the base number though.)

Answer 2

A) 3²·3³

E) 3^4·3^1

Explanation:

When multiplying numbers with exponents, keep the base the same and add the exponents.

So A and E would equal 3 to the fifth power.
