simplify (4.5x10^4)(2x10^3)

simplify

(4.5 x 1 0^{4}) (2 x 1 0^{3})

90000000 x^{2}

Solution steps

(4.5 x \cdot 1 0^{4}) (2 x \cdot 1 0^{3})

Simplify

4.5 x \cdot 1 0^{4} : 45000 x

= 45000 x \cdot 2 x \cdot 1 0^{3}

1 0^{3} = 1000

= 45000 x \cdot 2 x \cdot 1000

Multiply the numbers:

45000 \cdot 2 \cdot 1000 = 90000000

= 90000000 xx

Apply exponent rule:

aa = a^{2}

xx = x^{2}

= 90000000 x^{2}

- 2 e^{- x} sin (x)

x^{- \frac{1}{2} = x^{\frac{1}{2}}}

729 \cdot (324 \cdot 162)^{- 1} \cdot (- 13.5)

(\frac{1}{4}) (5^{- 2})^{4.625}

(6.67 \cdot 1 0^{- 11}) (75) (8.7 \cdot 1 0^{20})
