(7 x 7) - (5 x 3)
"Evaluate 7a" typically means to calculate the value of the expression by substituting a specific value for the variable "a." For example, if "a" is given as 3, you would substitute it into the expression to get 7 * 3, which equals 21. If no value for "a" is provided, the expression remains as 7a.
To evaluate an exponential expression, you need to substitute the values into the expression and perform the necessary calculations. For instance, if the expression is (2^3), you would calculate it as (2 \times 2 \times 2), which equals 8. If you provide a specific exponential expression, I can help with the evaluation.
To evaluate the expression (9c - 3) when (c = 10), substitute 10 for (c): [9(10) - 3 = 90 - 3 = 87.] So, when (c = 10), the expression (9c - 3) equals 87.
To evaluate the expression (3xy + 4y^3) when (y = 2) and (x = 5), substitute the values into the expression. This gives: [ 3(5)(2) + 4(2^3) = 30 + 4(8) = 30 + 32 = 62. ] Thus, the value of the expression is 62.
To evaluate the expression when ( n ) equals a specific value, you substitute that value into the expression in place of ( n ). For example, if the expression is ( f(n) = n^2 + 3n ), you would calculate ( f(7) ) by substituting 7 for ( n ), resulting in ( 7^2 + 3(7) ). Similarly, for ( n = 0.4 ), you would substitute 0.4 into the expression and compute the result. This process allows you to find the numerical value of the expression for those specific values of ( n ).
Take 3 and substitute into the expression given to you but not mentioned in the question here and evaluate the expression. "Sub and Solve" I say.

To evaluate 15k when k equals 3, you would substitute the value of k into the expression. Therefore, 15k becomes 15(3), which simplifies to 45. So, when k equals 3, 15k equals 45.
