simplify (3.42x10^6)(8.5x10^7)

simplify

(3.42 x 1 0^{6}) (8.5 x 1 0^{7})

2.907 E 14 x^{2}

Solution steps

(3.42 x \cdot 1 0^{6}) (8.5 x \cdot 1 0^{7})

Apply exponent rule:

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

1 0^{6} \cdot 1 0^{7} = 1 0^{6 + 7}

= 3.42 x \cdot 8.5 x \cdot 1 0^{6 + 7}

Add the numbers:

6 + 7 = 13

= 3.42 x \cdot 8.5 x \cdot 1 0^{13}

Apply exponent rule:

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

xx = x^{1 + 1}

= 3.42 \cdot 8.5 x^{1 + 1} \cdot 1 0^{13}

Add the numbers:

1 + 1 = 2

= 3.42 \cdot 8.5 x^{2} \cdot 1 0^{13}

Multiply the numbers:

3.42 \cdot 8.5 = 29.07

= 1 0^{13} \cdot 29.07 x^{2}

Convert element to a decimal form

1 0^{13} = 10000000000000

= 10000000000000 \cdot 29.07 x^{2}

Multiply the numbers:

29.07 \cdot 10000000000000 = 2.907 E 14

= 2.907 E 14 x^{2}

7 r^{3} (3 r^{2})

- 2 x (x^{2} - 1) e^{- x^{2}}

1.266 \cdot 1 0^{- 3}

x - 2 \cdot x - 7

3 e^{- 2 t} (- 30 e^{2 t})
