Answer:
area of the figure=1/2×16×7
=56 m²
Answer:
1/x^4
Steps:
(1/2x)^4 = <em>1/2^4x^4</em>
= 16 * 1/2^4x^4
Multiply fractions: <em>a * b/c = a * b/c</em>
= 1 * 16/2^4x^4
Multiply the numbers:<em> 1 * 16 = 16</em>
16/2^4x^4
Factor 16: <em>2^4</em>
= 2^4/2^4x^4
Cancel the common factor: <em>2^4</em>
= 1/x^4
