Step-by-step explanation:

Given expression:

13)

15)

Write the expressions in radical form.

Solution:

For an expression with exponents as fraction like

the numerator represents the power it is raised to and the denominator represents the nth root of the expression.

For an expression with exponents as negative  fraction like

We take the reciprocal of the term by rule for negative exponents.

So it is written as:

using the above properties we can write the given expressions in radical form.

13)

⇒   [Using rule of negative exponents]

⇒    [writing in radical form]

15)

⇒     [Since 2nd root is given as in radical form]

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
