In your laws of indices, when multplying numbers of the same base, you add their indices and when dividing you subtract. Therfore:
$\frac{y^{5} *y^{3}}{ y^{2} } = \frac{ y^{8} }{ y^{2} } = y^{6}$

Which expression is equivalent to 30 (1/2x - 2) +40 (3/4y-4)? (will add pic)

bixtya [17]

Answer:

Step-by-step explanation:

Given

30( $\frac{1}{2}$ x - 2) + 40( $\frac{3}{4}$ y - 4)

Multiply each of the terms in the first parenthesis by 30 and multiply each of the terms in the second parenthesis by 40.

= 15x - 60 + 30y - 160

= 15x + 30y - 220 → C
