Which expression is equivalent to (r^-7)^8

ahrayia [7]

Answer:

1/r^56

Step-by-step explanation:

Not sure if you did a typo there or what cus 7 x 8 should be 56

Whenever the power of a number is negative, you flip. So r^-7 becomes 1/r^7

Remove the bracket and distribute 8 to the power of 1 and r^7

1 to the power of 8 will still be 1, r^7 x 8 = r ^ 56

Simplify the expression.<br> - (m<br> m + 3n - 13)

natulia [17]

Answer:

$= - {m}^{2} - 3n + 13$

Step-by-step explanation:

$- (m \times m + 3n - 13)$

$m \times m = {m}^{1} \times m$

${m}^{1} \times {m}^{1} = {m}^{1 + 1} = {m}^{2}$

$- ( {m}^{2} + 3n - 13)$

$= - {m}^{2} - 3n + 13$
