simplify (-3sin(t))^2

Solution

simplify

(- 3 sin (t))^{2}

Solution

9 sin^{2} (t)

Solution steps

(- 3 sin (t))^{2}

Apply exponent rule:

(- a)^{n} = a^{n},

if

n

is even

(- 3 sin (t))^{2} = (3 sin (t))^{2}

= (3 sin (t))^{2}

Apply exponent rule:

(a \cdot b)^{n} = a^{n} b^{n}

(3 sin (t))^{2} = 3^{2} sin^{2} (t)

= 3^{2} sin^{2} (t)

3^{2} = 9

= 9 sin^{2} (t)
