Question

Упростите выражение:!!! ^ это значит степень!!! 7b ^-4 c * (-5b^3) * 8c ^-6

Answer 1

7b^-4c * (-5b^3) * 8c^-6=-280c b^3/ b^4c^6=-280/ bc^5

Answer 2

I can help you with math problems and other topics. To simplify the expression, you need to apply the rules of exponents and multiplication. Here are the steps:

- Rewrite the expression using parentheses and fraction bars: $$\frac{7b^{-4}c}{1} \times \frac{-5b^3}{8c^{-6}}$$ - Multiply the numerators and the denominators: $$\frac{7b^{-4}c \times -5b^3}{1 \times 8c^{-6}}$$ - Simplify the fractions by canceling out the common factors: $$\frac{-35b^{-1}c^7}{8}$$ - Rewrite the expression using negative exponents: $$-\frac{35c^7}{8b}$$

This is the final answer. I hope this helps.Ответь+подробно.+Упростите+выражение:!!!+^+это+значит+степень!!!+7b+^-4+c+*+(-5b^3)+*+8c+^-6
