Can anyone help me with this Matlab questions?

7. Calculate log4 25 +logs 34. You might need a change of base or two. Assign to p7 8. Use solve to solve 3r6-49. Assign to ps. 9. Use solve to solve 1 +4237a1- 6r2 -8r +7r*. Assign to ps. 10. A surveyer standing at point A sights two targets, one at B and one at C. He measures that target 5 pts 3 pts 3 pts] 4 pts B is 228 yards away, target C is 77 yards away and the angle between them is 21 degrees. Use solve and the Law of Cosines to find the distance between B and C. Assign to pi0. Note: Using solve applied directly to the LOC will yield both a positive and negative solution please do this! il. Use simplify to simplify (RTH)))) + (3-(5 + (3 (?)))). Assign to p11. 4 pts
