Solution steps

(4 \cdot 7)^{- 4}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

(4 \cdot 7)^{- 4} = \frac{1}{( 4 \cdot 7 ) ^{4}}

= \frac{1}{( 4 \cdot 7 ) ^{4}}

(4 \cdot 7)^{4} = 614656

= \frac{1}{614656}

15 x^{2} y + 20 x y^{2}

(5^{3})^{2} 5^{- 2} - 5^{3} 5

143 + 305 \cdot 70 W or l d

\frac{7}{( - \frac{1}{x} ) ^{2} - 3}

(x + y - 2) (x - y + 2)
