simplify 9x^4(4x^3)

Solution

simplify

9 x^{4} (4 x^{3})

36 x^{7}

Solution steps

9 x^{4} (4 x^{3})

Apply exponent rule:

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

x^{4} x^{3} = x^{4 + 3}

= 9 \cdot 4 x^{4 + 3}

Add the numbers:

4 + 3 = 7

= 9 \cdot 4 x^{7}

Multiply the numbers:

9 \cdot 4 = 36

= 36 x^{7}

e^{- \frac{1}{0.75}}

e^{- 20 (t)} (5 cos (40 (t)) + \frac{5}{2} sin (40 (t)))

e^{- 3 l n (y)}

\frac{4 π \cdot 9 \cdot 1 0 ^{4} \cdot 3.14 \cdot 1 0 ^{- 4}}{0.25} \cdot 1 0^{- 3}

7.84 \cdot 1 0^{- 7} \cdot (100 0^{2} - 25 0^{2}) \cdot 0.4 \cdot 160.17
