The answer to the problem. i don't know how to solve the exponents

When muliplying these terms you ADD the exponents so

7^0 * 7^4 * 7^16 = 7^(0+4+16) = 7^20 (NOTE you can any multiply when the base number, in this case 7, is the same)

so we simplify to

3^4 * 7^20

3^2 * 7^12

When dividing we SUBTRACT the exponents so 3^4 / 3^2 = 3^(4-2) = 3^2 and

7^20 / 7^12 = 7^8

so the answer is 3^2 * 7^8 < Option J

One yard is 3 feet. 1 foot is 12 inches. so there's 36 inches in one yard. now, with that, 36 divided by 3 is 12. twelve 3 inch segments in one yard. using this logic, two yards has 24, three yards has 36, four yards have 46. and, four and a half yards has 52 three inch segments
