(1.) Using exponential notation, we can write ^3√19 as …. (2.) Write the radical expression using exponents….
^7√ 2^2

(3.) Simplify each expression, and eliminate any negative exponents.
(7a/b^7)^-1

(4.) Simplify the expression and eliminate any negative exponent(s). Assume that all letters denote positive numbers.

it's both, now can you answer my most recent question?

answer: get jesus in your life

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
