simplify (4.2x10^8)(7.1x10^8)

simplify

(4.2 x 1 0^{8}) (7.1 x 1 0^{8})

2.982 E 17 x^{2}

Solution steps

(4.2 x \cdot 1 0^{8}) (7.1 x \cdot 1 0^{8})

Apply exponent rule:

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

1 0^{8} \cdot 1 0^{8} = 1 0^{8 + 8}

= 4.2 x \cdot 7.1 x \cdot 1 0^{8 + 8}

Add the numbers:

8 + 8 = 16

= 4.2 x \cdot 7.1 x \cdot 1 0^{16}

Apply exponent rule:

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

xx = x^{1 + 1}

= 4.2 \cdot 7.1 x^{1 + 1} \cdot 1 0^{16}

Add the numbers:

1 + 1 = 2

= 4.2 \cdot 7.1 x^{2} \cdot 1 0^{16}

Multiply the numbers:

4.2 \cdot 7.1 = 29.82

= 1 0^{16} \cdot 29.82 x^{2}

Convert element to a decimal form

1 0^{16} = 1.0 E 16

= 1.0 E 16 \cdot 29.82 x^{2}

Multiply the numbers:

29.82 \cdot 1.0 E 16 = 2.982 E 17

= 2.982 E 17 x^{2}

25 e^{- 0.15 (3)}

4 - 7 \cdot 4 + 7

- 55 e^{- \frac{3}{2}}

(x^{6} + 5 x^{4} + 3 x^{2} - 2 x) e n t re (x^{2} - x + 3)

89^{2}
