y=7^{-1/2}

y = 7^{- \frac{1}{2}}

y = \frac{1}{7 ^{\frac{1}{2}}}

Decimal Notation

y = 0.37796 \dots

Solution steps

y = 7^{- \frac{1}{2}}

Apply exponent rule:

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

y = \frac{1}{7 ^{\frac{1}{2}}}

3 x + 2 - 2 x - 3 = 0

7 (x - 4) - 3 = 46

k, y = a (x - h)^{2} + k

7 + 3 u = 4

lo g_{64} (2) = \frac{1}{6}
