(3^5)^2 : Multiply the exponents to get 3^10

Now you have 3^-10 x 3^-10

Multiply 3 x 3 = 9

When you multiply exponents with the same base, add the exponents together: -10 + -10 = -20

Answer: 9^-20

Select the correct answer. What are the values of x in this equation? `x^(2/5) + x^(1/5) + 1 = 3` A. 32, -1 B. 32, 1 C. -32, 1 D

mrs_skeptik [129]

x^(2/5) + x^(1/5) + 1 = 3

subtract 3 from each side

x^(2/5) + x^(1/5) -2=0

let m = x^1/5

m^2 +m -2 =0

(m - 1) (m + 2) = 0

using the zero product property

m=1 m=-2

replace m = x^1/5

x^1/5 =1 and x^1/5 = -2

take everything to the 5th powr

x^ 1/5 ^ 5 = 1^5 and x^ 1/5 ^ 5 = -2 ^ 5

x = 1 and x = -32

Choice C

C. -32, 1

if my cost price is $6300 and my selling price is $5000 then what would be my gain and gain percentage?

guajiro [1.7K]

Given :-

CP = $6300
SP = $5000

To Find :-

The gain and gain % .

Solution :-

Well there is no gain as you can see the CP > SP .So there is a loss . We can find the loss and loss% . As ,

$\longrightarrow$ Loss = CP - SP

$\longrightarrow$ Loss = $(6300-5000)= $1300

Now the loss% is ,

$\longrightarrow$ Loss% = Loss/CP * 100

$\longrightarrow$ Loss% = $1,300/$6300*100

$\longrightarrow$ Loss% = 13/63 * 100

$\longrightarrow$ Loss% = 20.63%

Hence the loss is $1300 and the loss% is 20.63%.

Determine whether the number is divisible by 3.give a reason based on the tests for divisibility 72

snow_lady [41]

72 is dividable by 3. It is divisible by 3 because when you add 7 and 2, you get 9. According to the tests for divisibility, if the sum of the digits is divisible by 3, then the whole number is. 9 is divisible by 3, therefore 72 is as well.
