simplify (2w^5)(8w^8)(5w^7)

simplify

(2 w^{5}) (8 w^{8}) (5 w^{7})

80 w^{20}

Solution steps

(2 w^{5}) (8 w^{8}) (5 w^{7})

Apply exponent rule:

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

w^{5} w^{8} w^{7} = w^{5 + 8 + 7}

= 2 \cdot 8 \cdot 5 w^{5 + 8 + 7}

Add the numbers:

5 + 8 + 7 = 20

= 2 \cdot 8 \cdot 5 w^{20}

Multiply the numbers:

2 \cdot 8 \cdot 5 = 80

= 80 w^{20}

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

(2 p^{3}) \cdot p^{3}

3 (- 2) e^{- 5 (3)}

e^{- 1650.6}
