simplify (810^2)(1.31.25^{-9})

simplify

(8 \cdot 1 0^{2}) (1.3 \cdot 1.2 5^{- 9})

139.58643 \dots

Solution steps

(8 \cdot 1 0^{2}) (1.3 \cdot 1.2 5^{- 9})

Apply exponent rule:

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

= 1 0^{2} \cdot 8 \cdot 1.3 \cdot \frac{1}{1.2 5 ^{9}}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= 1.3 \cdot \frac{1 0 ^{2} \cdot 1 \cdot 8}{1.2 5 ^{9}}

\frac{1 \cdot 8 \cdot 1 0 ^{2}}{1.2 5 ^{9}} = 107.37418 \dots

= 1.3 \cdot 107.37418 \dots

Multiply the numbers:

1.3 \cdot 107.37418 \dots = 139.58643 \dots

= 139.58643 \dots

(7 - x)^{0.5} (5.25 - 1.5 x)^{0.5}

0.000874 \cdot 0.00 3^{1.75} \cdot 2.45 7^{- 4.75}

e^{- (0.8)^{2}}
