The value B is 7. If we apply B=7 the answer is 17 for the expression 17×
Step-by-step explanation:
             The given expression is 17× 
  
Step:1
             Form an equation from given data,
             17× = 17..............................(1)
= 17..............................(1)
                                                          (∵ product equal to 17)
Step:2
             Check for alternatives by apply the value of B in eqn (1)
             Assume be value of B for check the equation
             B=1
             Equation becomes,
             17× = 2.4286 ≠ 17
 = 2.4286 ≠ 17
             Take, B=2,
             17× = 4.8571  ≠ 17
 = 4.8571  ≠ 17
             Take, B=3,
             17× = 7.2857 ≠ 17
 = 7.2857 ≠ 17
similarly, 
             B=7,
             17× = 17                        (∵ The product equals to 17)
 = 17                        (∵ The product equals to 17)
Result:
          So, the answer for B is 7.

Answer:
   8x +36 = 15
Step-by-step explanation:
The fractions can be made to disappear by multiplying the equation by their least common denominator. That number is 18.
   18(4/9x +2) = 18(5/6)
   8x +36 = 15
__
The solution is x = -21/8.
 
        
                    
             
        
        
        
For example, if the question is to simplify square root x^7, you do 7/2=3......1
so the answer would be x^3 times square root x
