i) 3

ii) (- 4)

iii) (1/2)

As we know that

b

(i) 3

(ii) (-4)

(iii) (1/2)

Simplify and express the result in power notation with positive exponent.

(i)

= (-4)

= (-4)

=1/ (-4)

= 1/2

=1/2

iv )

= (3

=3

=3

=3

=1/3

v) 2

= (2× -7)

= (-14)

=1/ (-14)

Find the value of

- (3
^{0}+ 4^{ - 1}) × 2^{2} - (2
^{ - 1}× 4^{ - 1}) ÷ 2^{ - 2} - (3
^{ - 1}+ 4^{ - 1}+ 5^{ - 1})^{0}

**Answer**

- (3
^{0}+ 4^{ - 1}) × 2^{2}= (1+1/4) × 4

= 4+1=5

= [(1/2) × (1/4)] ÷ (1/4)

= (1/8) × (4) =1/2

3.

= 2

=4+9+16=29

4. (3

=1 as a

Evaluate

Answer

Find the value of

5

5

5

So m+3=5

m=2

Evaluate

Simplify.
