simplify (4a)(3a^3)

Solution

simplify

(4 a) (3 a^{3})

12 a^{4}

Solution steps

(4 a) (3 a^{3})

Apply exponent rule:

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

a a^{3} = a^{1 + 3}

= 4 \cdot 3 a^{1 + 3}

Add the numbers:

1 + 3 = 4

= 4 \cdot 3 a^{4}

Multiply the numbers:

4 \cdot 3 = 12

= 12 a^{4}

e^{- 1.2 \cdot 2} (1 + 1.2 \cdot 2 + \frac{( 1.2 \cdot 2 ) ^{2}}{2})

(8.7 \cdot 1 0^{- 4}) (8.7 \cdot 1 0^{- 4} \cdot 2)^{2}

e^{- \frac{1}{10} \cdot 20}

(1 - x^{2})^{3} \cdot (1 - x^{2})^{3}

25 \cdot (17.3 \cdot 1 0^{- 6}) \cdot (90 - 25)
