3^8 and -12z^3 i think, i’m not sure tho so sorry if i’m wrong

For the first question. Lets first try and combine like terms.

This means we can combine the powers and make the expression shorter for our own likenesses. 

We can add 2 and 4. Which is 6.

Which leaves us with our new equation.

A: 3 to the 6th power (3^6)

I apologize but im not sure for the second question.

I do hope this helps.

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
