Answer:
The C++ statement for the given algebraic expression 5x^2 + 15k + y^-2 is ( ( 5 * ( x * x ) ) + ( 15 * k ) + ( 1 / ( y * y ) ).
Explanation:
To convert the given algebraic expression 5x^2 + 15k + y^-2 into the C++ statement without using the pow function is:
In the given algebraic expression, there are three expressions combined using the + operator.
The first algebraic expression is 5x^2.
Here, x has a power of 2, and 5 is multiplied by the result of x^2. x having the power of 2 means x is multiplied itself twice. The C++ statement for this algebraic expression is (5 * ( x * x)).
The second algebraic expression is 15k.
Here, 15 is multiplied by k. The C++ statement for this algebraic expression is (15 * k).
The third algebraic expression is y^-2.
Here, x has a power of -2. it means . The C++ statement for this algebraic expression is (1/ (y * y).
The combination of all the three C++ statement is (5 * ( x * x)) + (15 * k) + (1/ (y * y).
