simplify (-2*sqrt(15))^2

Solution

simplify

(- 2 \cdot 15)^{2}

Solution

60

Solution steps

(- 215)^{2}

Apply exponent rule:

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

if

n

is even

(- 215)^{2} = (215)^{2}

= (215)^{2}

Apply exponent rule:

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

(215)^{2} = 2^{2} (15)^{2}

= 2^{2} (15)^{2}

2^{2} = 4

= 4 (15)^{2}

(15)^{2} = 15

= 4 \cdot 15

Multiply the numbers:

4 \cdot 15 = 60

= 60
