simplify (3x10^4)(2.1x10^3)

simplify

(3 x 1 0^{4}) (2.1 x 1 0^{3})

63000000 x^{2}

Solution steps

(3 x \cdot 1 0^{4}) (2.1 x \cdot 1 0^{3})

Simplify

3 x \cdot 1 0^{4} : 30000 x

= 30000 x \cdot 2.1 x \cdot 1 0^{3}

1 0^{3} = 1000

= 30000 x \cdot 2.1 x \cdot 1000

Multiply the numbers:

30000 \cdot 2.1 \cdot 1000 = 63000000

= 63000000 xx

Apply exponent rule:

aa = a^{2}

xx = x^{2}

= 63000000 x^{2}

(2 x 1 0^{- 4}) (8.1 x 1 0^{- 1})

4 π (0.01)^{2} (0.01)

[(x + 1)^{2}]^{^{'}}

(4, - 2)^{2} (- 1, 2)^{2}

\frac{10}{π} (π + 1)
