4^-2 x 7^-2 equivalent expression

Savatey [412]

Answer:

Not sure exactly which equivalent expression you are looking for but my goal would be to write it without the negative exponent.

$\frac{1}{28^2}$

Step-by-step explanation:

They have the same exponent and it is multiplication.

There is a law of exponent that says $(a \cdot b)^x=a^x \cdot b^x$ .

So we have $4^{-2} \cdot 7^{-2}$ equals $(4 \cdot 7)^{-2}$ .

Let's simplify (4*7)^(-2).

Since 4*7=28, we can say $(4*7)^{-2}=(28)^{-2}$ .

Some people really hate that negative exponent. All that - in the exponent means is reciprocal. So $28^{-2}=\frac{1}{28^2}$ .

Kiran read for x minutes, and Andre read for 58 more than that. Write an equation that relates the number of minutes Kiran read

bogdanovich [222]

Answer:

$0.017y=0.017x+0.97$

Step-by-step explanation:

Let us assume that,

number of minutes read by Kiran is = x minutes.

number of minutes read by Andre is = y minutes.

Andre read for 58 minute more than that of Kiran.

Converting minute to hour we get,

$x\text{ minutes}=\dfrac{x}{60}=0.017x\text{ hour}$

$y\text{ minutes}=\dfrac{y}{60}=0.017y\text{ hour}$

$58\text{ minutes}=\dfrac{58}{60}=0.97\text{ hour}$

So the relationship between x and y will be,

$0.017y=0.017x+0.97$
