Question : 18 of 75

Marks: +1, -0

The value of

8^{2}+\sqrt{10^{2}}-1\sqrt{16}-5=

Solution:

Concept:

This simplification uses the order of operations, BODMAS, to evaluate powers and square roots first.

Explanation:

First evaluate each term separately.

8^{2} = 64

\sqrt{10^{2}} = \sqrt{100} = 10

1\sqrt{16} = 1 \times 4 = 4

Substitute these values into the given expression:

64 + 10 - 4 - 5

Add the first two terms:

64 + 10 = 74

Now subtract the remaining values:

74 - 4 - 5 = 65

So the value of the expression is

65

Answer:

Option A,

65
