(5) to the 7 over 3 power

Maksim231197 [3]

$5^{7/3} = 42.75$ (approximately)

using the formula $x^{a/b}=\sqrt[b]{x^a}$ we can solve the problem

so we rewrite it as $\sqrt[3]{5^7}$ and get ~42.75

nevsk [136]

Answer:

See below

Step-by-step explanation:

Yes it is possible

First way is:

$1-sin^2x= (1+\sin x)(1-\sin x)$

Second way is:

$1-sin^2x= \cos^2x = \cos x. \cos x$
