simplify 9b^{2-a}(3b^6)

Solution

simplify

9 b^{2 - a} (3 b^{6})

Solution

27 b^{- a + 8}

Solution steps

9 b^{2 - a} (3 b^{6})

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

b^{2 - a} b^{6} = b^{2 - a + 6}

= 9 \cdot 3 b^{2 - a + 6}

Add the numbers:

2 + 6 = 8

= 9 \cdot 3 b^{- a + 8}

Multiply the numbers:

9 \cdot 3 = 27

= 27 b^{- a + 8}
